LIFE-BOAT.

Be it known that I, JOHN E. ALLEN, a

Subject of the King of England, residing at Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Life-Boats, of g of the bilge keels are rigidly, secured longlwhich'the follo ing is a specification.

The principal object of this invention is the provision of marine craft having chiefly in view the saving of human lives from sinki I I wing members thereof are slde-lights 18 and ing vessels or wrecks.

It has for a further object the provision; of accommodations for numbers of peoplei at a time and to the consideration of theircomfort while being transported to a place of safety. I

A still further object is the provision of: improved mechanism arranged to be ma nipulated by a screw for propelling and steering the craft.

The invention consists in the novel construction and adaptation of devices, as will be hereinafter described with reference to the accom )anying drawings, in'which Figure of a life-boat embodying my invention. Fig. 2 is a midship cross sectional view of Figs. 3 and 4 are detail sectional views illustrating the boat ventilating devices in two assumed positions.

The reference numeral 5 designates the hull proper of the boat inclosed by inner and outer shells 6 and 7, respectively, and spaced apart to afford water-tight compartments 8 at the sides and bottom, and compartments 9 above and below the part 10 which constitutes the deck. Wing members are provided'exteriorly of the shell 7 and to the sides of the hull propel and are each formed of an outer casing comprised of side plates 12 and deck plates12 with partitions 13. I Said partitions are severally disposed to incline inwardly at the top and the-casing plates 12 are, intermediate the adjacent partitions, curved inwardly, as at 14 in Fig. 2, and are likewise curved between the lowermost partition -.upon each side and the juncture therewith of the plates 12 with the shell 7 below.

Extending transversely between the shells 6 and 7 are frame elements which subdivide the aforesaid compartments 8. In like manner transverse divisional frames or plates serve with the partitions 13 in aifording a plurality of relatively small compartments is a longitudinal vertical section employed in turning the crank'sin;efl'.ectih Specification of Letters Patent.

- within said wings. For longitudinal stiffening of the hull a centrallydisposed keel 15 and bilge heels are provided. The latter comprising plates 16 arranged to be. normal with respect to the hull surfaces at which so they are secured and upon the inboardsides tudinally extending concavo coiivex plates 17, as represented in Fig. 2.

In the hulland above the height- 0f the 5 Said shaft is driven from manually rotated pulleys 27 by endless belts 28 passing-about fairleader pulleys 29 and pulleys 30 upon the propeller shaft. 1 The pulleys 27 are mounted upon axles 31 and are severally 39 provided with anoperating crank 32. 5 Suitably positioned bench seats 33 arewdesirably provided for the convenience of the persons the boat-propulsion.

Rudders 3 1 and 35 are provided a new bow and stem ends of the boat and iup'on the respective posts are tiller yokes 36 which are operatively connected with a steering. wheel 37 by lines, such as 38. The steeringwheel is located above a platform 39 ar ranged so that the steersman may have a view through the side-lights 19 provided in the foremost of the turrets 20.

Ventilation for the interior of the boat is obtained through the agency of two or more tubes 40 extending through the deck and at a distance from each other. Each such tube (see Fig. 3,) above the deck is provided with a bend 41 so that the extremity 42 of the tube will be directed downwardly when the vessel is in an upright condition. Within each tube are two truncated conical plates 43 and 44 which are disposed at different elevations and are provided with con trally arranged openings 15 and 46. For the upper of these openings there is provided a flotative ball-valve 47 which upon being submerged in water is caused to close the opening thereabo the o ening 46 there is* provided a valve 48 which is mounted foroscillation upon a spindle 48 having an arm 49 for a depending weight 50 which is arranged to retain the valve open until the vessel heels over to a considerable angle.

In Fig. 4 is'represented a ventilator as it would appear when inclined and with .4 the two aforesaid valves in operation to close .10

f The annular channels 51 about the plates the respective openings.

43 and 44 are connected through water es -.c ape openings 52 with a drain-pipe 53 for carrying oil the water which may be entrained in the respective tube.

-54 is a valve provided in the pipe 53 for controlling the flow of water through the latter.

To one of the ventilator tubes is connected sidered as ollows: The wing compartments aflord buoyant moments to serve to maintain the vessel in an upri ht position with 'respect; to the water sur ace'and supplemental to the stability inherent to the hull pro er and in consequence thereof there is no ikelihood of the vessel upsetting. The

rolling of the vessel is to a large extent gcalled metacentric height; and the rolling overcome by the relatively high position occupied by its center of gyration; or sois further, retarded through the employment [is j toryieflect due to the resistance of the plates the wing casings 12, taken with the contribu Witnesses tudinal girders to make the vessel extremely rigid against longitudinal flexure, The incllnation of the partitions 13 in the wings afford compartments which would be unlikely to fill through the admission of water by any punctures had in the casing plates 12, as the inverted 'pockets, so to speak, which are produced in the angles a, Fig. 2, wouldrespectively contain quantities of air down to the level of any puncture that may occur in such plates.

Having described my invention, what I claim as new and desire to secure by Let ters-Patent, ,is

1. In a marme vessel, the. combination with the hull (proper, of wing members disposed longitu mally and exteriorlyofsai d hull, and downwardly to respectively divide the same intoa pluand outwardly'in-- clmed' partitions withm said wing members rality of compartments each of said oompartments' having the outer wall thereof concavo-convex in-contour.

2. Afmarine vessel comprising a closed hull having water tightrompartments at the bottom, sides and top thereof, said hull further-provided at its top with a plurality of turrets, one of said turrets being larger than the remaining turrets and provided with an entrance and further provided with an outlet whereby access can be had to the interior of the hull, a keel for the hull and a pair of outwardly inclined bilge-keels, each having on its face a concavo-convex plate,

and wlngs provided at each side of the hull, said wings embodyin water tight compart- 'ments, each having t e outer wall thereof concavo-cpnvex in contour.
